Did I overreact to my MIL’s attempt to throw a memorial for my stillborn daughter?

So bear with me cause I’m gonna have to give quite a bit of backstory here. Me and my husband have been married nearly 4 years. He gets along well with my parents but unfortunately his family seems to hate me. The 1st time he took me to meet them, his mom thought I was too common and that the dish I brought sucked. She didn’t say these things to me but rather to my husband in private. When we got married, G immediately started asking about when we would start trying to have kids. She was also very controlling of the wedding planning and in particular my dress. I had a pretty amazing wedding but she definitely hurt the experience and since then I’ve decided I just don’t wanna associate with her. Unfortunately that wasn’t entirely possible since my man is a mama’s boy and has always excused her behavior.

Whenever they’d come to us or we went to them, G was always badgering me about babies. It got even worse when hubby’s sister started having kids. She managed to have 3 kids in 5 years. Whereas I’ve managed none despite 2 good years of effort. I can definitely tell that this has angered G as now whenever we’re together she makes me feel so inadequate. G constantly praises M while ignoring all my accomplishments. M herself seems to have a superiority complex and loves making snarky comments at my expense.

So unfortunately, nearly 3 months ago I had a stillbirth. She was 6 months along and my 1st pregnancy. Obviously it was a devastating loss for me and my husband. My baby girls due date is in 6 days and I’m dreading the day. I’ve thought about going to her grave and talking to her, maybe even reading bedtime stories to her. I haven’t been to her grave since the funeral so it’s gonna be really difficult to go, but I feel like I owe it to her.

Unfortunately, hubby has decided to set up a memorial service at his parents house in honor of our daughter on that day and didn’t even think to ask me. He says it’s cause I’ve been so emotionally distant and he thinks being around family will be good for me. I blew up at him and said there’s no way I’m doing that. Being around M and especially G at this point would kill me. I told him he can go to his parents while I spend the day doing my own thing. Hubby says I’m being very rude. G called me Saturday and said that if I don’t show up it’ll be just another thing I’ve done to dissapoint her
